Introduction to Offshore Decommissioning and Restoration

WAODR77
(Engineering)

Outstanding Features

Looking through the lens of the issues that dominate today’s industry, participants will increase their familiarity with the basic principles of Offshore oil and gas decommissioning and restoration processes. Focus will be on learning from a real world operational point of view, rather than theory.

Course Overview

Starting from little to no knowledge of the processes from planning to execution of an offshore decommissioning project, the course offers a high level perspective of elements such as optioneering, scheduling, budget development, regulatory and stakeholder identification and management. The course covers facility late life, post CoP, maintenance and required systems through to facility removal and disposal and post removal site environmental monitoring for fixed, floating and subsea production and export systems.

Target Audience

This is course is suitable and beneficial for all non-technical and technical alike, along with more experienced people that require a broader understanding of the decommissioning and restoration of offshore oil and gas facilities.

You Will Learn How to

Describe the Decommissioning ProcessExplain the Working Principles of the equipment used to rig down dismantle, remove and transport oil and gas facilities from depleted / uneconomic oil and gas leasesUnderstand the processes related to Facility Late Life Maintenance Identify contributing factors to planning and budgeting development Describe option development and selectionUnderstand environmental impacts Recognize regulatory requirements from around the globeAppreciate the consequences of decommissioning gone wrong
